Finally. A downpipe for the 2008 STi/WRX and Legacy GT with the quality/fitment expected from MadDad. This "shorty" DP will mate with the last factory cat pipe, leaving you with the least restrictive factory cat,(the one that can be seen during visual inspections). True divorced wastegate design with separtor flange and dedicated wastegate dumptube. The pipe also includes an auxiliary 02 bung in the head for running a wideband af gauge or for dyno tuning sessions. Hand TIG welded with pride. This pipe is manufactured 100% in the U.S.A

I installed the "Shorty" 08+ DP on my 2011yr WRX sedan over a month ago and reflashed the car to the Cobb Stage 2 pluss "SF" intake (off the shelf) tuning map. The car has been running great and am very satisfied with the DP. I decided to keep the stock main or rear most cat. and the stock cat-back exhaust installed at this time mainly do to the overly aggresive vehical inspections they have in this state. The best thing is that I get increased performance with only a slight increase in noise, just the way I like it. The only thing I would improve on the pipe is to make it fully in 304 stainless not just the flanges but keep the unpolished for stealth.

Great DP for a stealth setup

I am running the stock main cat and catback connected to the shorty DP.

I purchased this used and the DP held up great and looks almost new. It seems to be very well made.

I was looking for an exhaust setup so I could go "stage 2" but didn't want something loud. So far this DP has worked great for me and I am hitting all the boost targets. I have not dynoed the car yet, so I am unsure if the shorty lacks power compared to a full DP. I daily drive my car and do not planning on seriously tracking it.

If you are looking for something loud look for a different solution than me. If you want stealth power, think about this shorty DP as an option.
